Maintenance Strategy of Deteriorating RC Bridge Piers in Consideration of Seismic Risk

Abstract

In this paper, the maintenance management is described for the existing and aging RC bridge piers. The maintenance scenarios of aging and deteriorating RC bridge piers are considered based on various repairing methods. The life-cycle cost analysis is carried out, including the seismic risk under unexpected large earthquake. If the aging and deteriorating RC bridge piers are not maintained effectively, their seismic performance decreases, and the seismic risk increases. The life-cycle cost analysis with the seismic risk leads to the efficient maintenance plan of RC bridge piers.
